The NBA plans to officially announce the participants next week for the Feb. 16 event in Los Angeles. Lakers forward Larry Nance Jr. is a strong candidate to be the fourth participant, but has yet to make a final decision, league sources said.

Oladipo has had an All-Star-caliber year in his fifth NBA season, averaging 24.2 points and 5.2 rebounds in 42 games for Indiana. Oladipo was runner-up to Chicago Bulls guard Zach LaVine in the 2015 dunk contest in New York.

For Gordon, this would be his third consecutive appearance in the event. Gordon is having a breakout campaign, averaging 18.4 points and 8.2 rebounds this season. In 2016, Gordon and LaVine dueled in one of the all-time dunk performances, with LaVine earning the trophy.

Smith, a high-flying rookie, has averaged 14.8 points and 4.6 assists in 39 games. He was the No. 9 overall pick in the 2017 draft.

Nance is regarded as one of the league’s top athletes, and his father, Larry Nance, won the dunk contest in 1984.
